COFFEE COMPOUND ANUPROCESS OF MIAMI-NG SAME,

SPECIFICATION forming part of Letters Patent No. 680,889, dated August 20, 1901. Application filed November 12, 190D. Serial No. 36.182. (No specimens.)

Y the city of Minneapolis, county of Hennepin,

. coffee or like composition and State of Minnesota, have invented a certain new and Improved Coffee Composition and Process of Manufacturing the Same, ot' which the following is a specification.

My invention relates to coifee and like maferials from which beverages are made, and has to do particularly with a new article of manufacture from coffee and a process of 'man ufacturing lthe same.

The object of my invention is to-fpreserve coffee orlike material and adapt the same to the making of the beverage almost instantaneously and without the usual process of boiling. l

A particular object of the invention is to prepare the coifee for instant use and at the same time retain thefullvalue thereof as a beverage substance and also the actual money value of the material when compared weight for weight with the coee that is in common use. I accomplish this by pulverizing the coffee or like bean with sugar ora like substance, the presence of which in the beverage is not objectionable.

`My invention consists generally in a new containing sugar,

which in turn contains a large proportion of both the essential and fixed oils of the coffee; and my invention further consists in a process of manufacturing my novel codec composition, and resides, primarily, in subjecting the coffee-beans to-a separating process, whereby the oils are separated from the cel lular tissue without danger of infiltration of .said tissue and insuring the infiltration of sugar. v i

The invention will be more readily understood by reference to the accompanying drawing, forming a part of this specification.

The nu meral'2 represents a suitable bin or v` hopper for roasted coffee or other material,

such as cocoa. Frein this bin the coffee- -beans are fed to a bur-mill 3, wherein the codec is coarsely ground or granulated, the granulated coffee dropping into the storagebin 4.' This bin 4 and another bin 5 for sugar` are conveniently locatedA above a track 6,

upon whichtare trucks 7 and '8 to receive the 1 ground coffee and granulated sugar, respectively. The track 6 leads to a weighing scale 9, whereon the contents of each truck may be weighed to secure the proper proportions of the two materials. Beyond the scale is a chute or hopper l0, through which the contents of the trucks may be deposited in a suitable mixer 11. After this mixer is loaded it is closed and is thereafter rotatedlong 6o enough to thoroughly mix the granulated materials. After the materials are mixed the mixture is dumped from the mixer into the hopper l2 beneath. From, this hopper the material is drawn off int'o the hopper 13 65 and a separator 17. The separator 17 is pref- 7o erably of the conical type, and from this separator the material is discharged intothe receiving-box 18, on top of which are a series of cloth frames l9,.through the cloth upon which the air that is employed in the pulverizing-mill and in the process of separation is discharged, leavingv the tine material in the box. The pulveri'zer that I prefer is of the rotary type, wherein the beaters do not engage with the grinding-surface, operating only to beat 8o and .break the particles of material fed there to, centrifugal action having much to do with the above process of pulverization and separation, which latter process may be otherwise termed the' process of grading, by which 85 only particles of a desired size are permitted to escape from the pulverizer..` As the comparativel y coarse material from the hopper 13 reaches the beaters of the mill and is acted upon thereby, the granulated coffee is broken 9o into line particles, the same and the sugar beging reduced to' an impalpable powder. Meantime the oils and the like in the cotee which'are forcibly liberated and extracted from the cells of the coffee-beans are forced 9v into intimate contact with the particles of. sugar, which take up or absorb saidoils and essences, and the resultant product which is deposited in the receiving-box is absolutely dry and retains its powdered form instead of roo being sticky, oily, or paste1ike.` This is true to such an extent that whereas ordinarily- .terial containing the major portion'of the V vpulveried coffee when placed upon a plate,

clean paper, or, cloth will soon stain the same my product may be placed or packed in paper or cloth indefinitely and will Anot stainor discolor the same, the complete absorption and retention of the codec-oils by the sugar being thus demonstrated. To secure this result, I prefer to employ a proportion of from fifty to thirty-three per cent. of sugar in the composition, and l' iiud that a greater cquantity of sugar is required when coiee of a low grade is used than when the grade is high. It is .Ils

ulated by the length of time-say from one to five minutes-that it is allowed .to stand or brew.

vHaving thus l described my invention, l claim as new and desire to secure by Letters Patentf l -1. The herein-described beverage compositionr containing pulverulent bean material and pulveruleut absorbent material in sub' stan-tially the proportions named, thoroughly admixed, and the particles of absorbent mal' position of coffee or the like, that consists in y mixing'a suitable absorbent material with original oils of said bean material, substantially as described.
